Hundreds of different reactions occur in the stratosphere, among them reactions that destroy the Earth's ozone layer. Table below lists several (second-order)  reactions of Cl atoms with ozone and organic compounds; each is given with its rate constant.

For equal concentrations of Cl and the other reactant, which is the slowest reaction? Which is the fastest reaction?

The rate constants for the reactions of atomic chlorine and hydroxyl radical with ozone are given by 3 x 10-11e-250/T and 2 x 10-12 e-940/T where T is the temperature in Kelvin. Calculate the ratio of rate of ozone destruction by atomic chlorine to the rate of ozone destruction by hydroxyl radical in the Antarctic ozone hole, in which the temperature is -80 oC and the concentrations of atomic chlorine and hydroxyl radical are equal. Assume that the reaction of ozone with the X. species ( either atomic chlorine and hydroxyl radical) is rate determining.

Free radicals areimportant in many environmentally significant reactions. Forexample, photochemical smog, which forms as a result of the actionsof sunlight on air pollutants, is formed in part by the followingtwo steps.

NO2 ---UV Light--> NO+ O

O + O2 -->O3

The product of thisreaction, ozone, is a pollutant in the lower atmosphere. Ozone isan eye and lung irritant and also accelerates the weathering ofrubber products. write Lewis strucktures of each of the reactantsand products in the preceding reactions


If possible I would like adetailed description with an answer so I can try to understand howit was worked and practice using it as a reference. Any help wouldbe greatly appreciated. I have another question that I need to posta picture with but I cant seem to get it to let me. its 36.8 kb anda j peg photo, is there a good way of doing this?

Sorry long question but Ireally would apretiate any help Im so dang confused
